I just created an Audio Spectrum Analyser app and it’s proved very popular. Turn your Android device into an audio spectrum analysis tool and break into safes – um, please don’t use it for that 😉 The app uses a Fast Fourier Transform (FFT) algorithm to analyse sound and has some features not found in similar apps (such as exporting audio snapshot data). Check it out!

For those interested in helping me correct or add more translations, see the github repo here.

How to use it

There are many uses for spectrum analyzers, such as:
• Assessing environmental noise for health and safety
• Sound checking speaker setups, PA systems and in-car stereos
• Identifying audio signals obscured to the human ear by noise
• Testing the microphone on your device
• Comparing the quality of different brands of headphones
• Testing signal generators
• Tuning musical instruments
• Measuring audio signals just outside human perception. As people age over 20 years, their aural perception range drops well below 21 kHz
Speccy has also been used to find gas leaks and even hunt ghosts, apparently!

For calibrating audio equipment or mixing, have a read of this article, this one, or watch this useful video:

I’ve started developing a new app for learning Thai language. A very early Beta version is available for testing here – Android only at the moment. Let me know if there’s particular features and content you’d like to see in there 🙂

I created this app mainly as a tech demo of Augmented Reality and somewhat for my own benefit when going out drinking.

I wanted to see how many calories and how much alcohol was in what I’m drinking. But barcode scanner apps often don’t work in a dimly lit pub, when you don’t have an internet connection, or when the barcode label is a bit wrinkled. So I created Beer Goggles. Continue reading Beer Goggles AR app→
